“Irresponsible” Russian Anti-Satellite Test Creates Orbital Debris Field, Endangering the Space Station and Crew

The debris not only threatened the crew and the ISS today, but might continue to cause issues for the ISS– along with other satellites and launches– for at least five years.
” Russias reckless and dangerous behavior endangers the long-term sustainability of … deep space and plainly shows that Russias (claims) to oppose the weaponization of space are disingenuous and hypocritical,” State Department spokesman Ned Price told press reporters at a briefing today.
In a declaration, NASA Administrator Bill Nelson stated, “Im outraged by this careless and destabilizing action. With its storied and long history in human spaceflight, it is unthinkable that Russia would endanger not just the American and international partner astronauts on the ISS, but also their own cosmonauts. Their actions are hazardous and reckless, threatening also the Chinese area station and the taikonauts on board.”

The ruined satellite, Kosmos-1408, appears to have actually separated either late Nov. 14 or early Nov. 15, based on federal government and industrial tracking data. The satellite has actually been in orbit considering that 1982 and is no longer functional. Sources stated the satellite weighed about 2,000 kgs (4,400 lbs) and was last tracked in an orbit about 485 kilometers high.

Early Monday, November 15, 2021, the International Space Station Flight Control group in Houston told the team that due to a to satellite break up, a particles field was produced near the stations orbital course. The cosmonauts and astronauts were informed to “shelter in location” on board the Soyuz and SpaceX pills attached to the ISS.
What emerged as the day endured is that the debris field was the result of a “devastating” test by Russia of an anti-satellite rocket system against among their own satellites. Specialists from the US Space Command state the test led to “over fifteen hundred pieces of trackable orbital particles” which could remain in orbit for several years.

An approach of debris is considered “close” just when it gets in an imaginary “pizza box” shaped area around the station, measuring 0.75 kilometers above and listed below the station and 25 kilometers on each side (2,460 feet above and below and 15.6 by 15.6 miles). Thrusters on the ISS can move the station out of the method of orbital particles, if the particles has actually been tracked or is understood about with adequate lead time.
Devoted debris shields on the ISS can withstand particles as big as 1 cm in size. It is understood that small pieces of particles have already clashed with ISS on numerous occasions, however no accidents to date have actually affected the security of the team or the operation of the mission.
For the most current regarding this event, orbital particles specialist and Harvard astronomer Jonathan McDowell is providing updates on Twitter relating to the particles field and how it will affect items in low Earth orbit.

The crew was awakened and directed to close the hatches on numerous external modules on the station, including Columbus, Kibo, the Permanent Multipurpose Module, Bigelow Expandable Activity Module, and Quest Joint Airlock.
NASA said an extra preventive measure of safeguarding the team was executed for two go through or near the area of the debris cloud. The team members made their method into their spacecraft shortly before 2 a.m. EST and stayed there till about 4 a.m. The area station is going through or near the cloud every 90 minutes, but the requirement to shelter for just the second and 3rd passes of the occasion was based upon a risk evaluation made by the particles office and ballistics professionals at NASAs Johnson Space Center in Houston.
The crew was also directed to move any sleeping quarters to the interior parts of the space station until more notice. Hatches between the U.S. and Russian sectors remain open.
NASA astronauts Tom Marshburn, Kayla Barron, Raja Chari and European Space Agency astronaut Matthias Maurer took shelter in their SpaceX Crew Dragon spacecraft, while Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov, in addition to NASA astronaut Mark Vande Hei, boarded the Soyuz spacecraft. While those spacecraft brought the team on board and will be utilized to bring them back to Earth again, both spacecraft can be used as lifeboats in any emergency situation.

With its storied and long history in human spaceflight, it is unimaginable that Russia would threaten not just the American and worldwide partner astronauts on the ISS, however likewise their own cosmonauts. Their actions are reckless and hazardous, threatening as well the Chinese area station and the taikonauts on board.”
NASA said an extra precautionary measure of sheltering the team was executed for 2 passes through or near the vicinity of the debris cloud. The crew members made their way into their spacecraft quickly prior to 2 a.m. EST and stayed there up until about 4 a.m. The area station is passing through or near the cloud every 90 minutes, but the requirement to shelter for only the 2nd and 3rd passes of the occasion was based on a danger evaluation made by the debris workplace and ballistics specialists at NASAs Johnson Space Center in Houston.
